In the recent weeks, Giant Hogweed (also known as Giant cow parsnip) has been found on Davis Campus near the pond. Giant Hogweed grow 3 to 4 metres in height and when in bloom, carries numerous small, white flowers that form an umbrella shape. The stem also contains coarse hairs (see the photo below, right).
The clear watery sap of Giant Hogweed contains toxins that can cause severe dermatitis (inflammation of the skin). You can get severe burns if you get the sap on your skin and the skin is then exposed to sunlight. Symptoms occur within 48 hours and consist of painful blisters. Purplish scars may form that last for many years. Eye contact with the sap has been reported (in the media and by various web sites) to cause temporary or permanent blindness. If you get sap on your skin wash the area well with soap and water. Keep the affected area out of the sun. If photo dermatitis (inflammation of the skin caused by exposure to sunlight) occurs, see a doctor. If you get sap in your eye, flush your eye with water immediately and see a doctor immediately.
If you spot Giant Hogweed, avoid the area and report the sighting to Security (ext. 4344) immediately.
Thank you.
